NQIMPRVOVEIV'IENT IN BARBED-JRON FENCES.

' Specification forming part of Letters Patent No. 178,195, dated May 30, 1876; application filed April 8, 1876.

To all whom it may concern:

Be it known that I, ELIJAH Sins, of' Aurora, in'the county of Kane and State of 1lli-- from which my fence-bar is rolled. Fig. 2-

represents the shape assumed after passing through first process of rolling. f represents a cross-sectionof same. Fig. 3 represents the bar and barbs before being twisted. Fig. 4 represents the barbed twisted fence-bar ready for use, and Fig. '5 a cross-section of same.

I take a bar of iron of suitable size, as represented by Fig. 1, heat and pass it through the rolls of rolling-mill, and give it the shape represented by Fig. 2. It then passes immediately into and through a machine, which I call my barb-cutter, which receives it from the rolls, and gives the shape represented by Fig. 3. The barbs a are cut and pointed while passing through this machine. The barbed bar I), now formed, passes at once into a machine, which twists the barbed bar, so that barbs. project in all directions in a spiral line around the bar.

.The cutting of the barbs and twisting the bar-can be done rapidly. If. it is desired to pass a dozen bars through the rolling-mill at one time, the barbs can be cut and bars twisted 'in all directions.

' In Fig. 2, I have shown the bar beveled or wedge-shaped in cross-section along its whole length, to give the advantage of sharp points V to the barbs, which are formed by cutting out, at intervals, the metal from one side of the bar, and left to project from one side of the bar at suitable distances apart.

The twisted barbed fence-bars are made in sections of sixteen or twenty feet, or any. desired length.

As I propose to patent the herein-referredto machinery, by, which I produce my new twisted barbed fence-bar, adescriptiou .ofsuch machinery is deemed unnecessary here, and I make no claim thereto in this specification.

I claim- 1. The metallic fence-rod t, having plane faces, and provided with barbs a, integral therewith, all projecting from one face, said rod twisted to arrange the barbs spiral] y around it, as herein set forth.

2. -A twisted barbed fence-bar, the barbs being at intervals upon one side of.a plane-faced bar, tapering orwedge-shaped in its crosssection, and pointed, substantially as herein set forth.

In testimony whereof 'I have aflizred my I signature in the presence of two witnesses.

ELIJAH SIMS.
